ABSTRACT
BACKGROUND:
Normative values of sagittal alignment are used as references for the diagnosis and treatment of spinal pathologies. There are currently no reference values for the normative sagittal alignment of Lebanese subjects. The objective is to describe normative values of full body sagittal alignment parameters in asymptomatic Lebanese adults and to compare the sagittal alignment of this population to that of populations of various origins.METHODS:
Included subjects were aged 18 to 28 years old. Each subject underwent a full body biplanar X-ray exam with measurement of spine, pelvis and lower limb parameters of sagittal alignment. The sagittal alignment of the Lebanese population was compared to that of other ethnicities, previously reported in the literature, using one-way ANOVA.RESULTS:
Ninety-two asymptomatic Lebanese young adult volunteers (48 males, 44 females, age=21.5±2.2 years) were enrolled in this study. The mean curvature in the cervical spine was kyphotic (-4.3°) in women, while it was lordotic in men (5.4°). Men were found to be significantly more kyphotic than women (-58.3° vs. -53.0°; p<0.01) but both sexes were found to have similar lordosis (61.6°) and pelvic incidence (52.0°). Lebanese subjects had intermediate pelvic incidence compared to other ethnicities but showed significantly higher thoracic kyphosis (p<0.01) and lumbar lordosis (p<0.01) compared to all other ethnicities.CONCLUSIONS:
This study established reference normative values for young adult Lebanese subjects. Most women were found to have kyphotic cervical spines. The sagittal alignment of Lebanese subjects differed significantly compared to that of other ethnicities. LEVEL OF EVIDENCE Level IV - cross sectional study.Key words
